\section{Getting Started}
\subsection{Installation}
\begin{itemize}
\item Lua\TeX, version 0.65.0-beta or later.\\
If you are using \TeX~Live\ 2011 or W32\TeX, you don't have to worry.
-\item The source archive or Lua\TeX-ja, of course{\tt:)}
+\item The source archive of Lua\TeX-ja, of course{\tt:)}
\end{itemize}
The installation methods are as follows:
\url{http://git.sourceforge.jp/view?p=luatex-ja/luatexja.git;a=snapshot;h=HEAD;sf=tgz}.
\end{flushleft}
\item Extract the archive. You will see {\tt src/} and several other sub-directories.
-\item Copy all the contents of {\tt src/} into your TEXMF trees.
+\item Copy all the contents of {\tt src/} into one of your \texttt{TEXMF} tree.
\item If {\tt mktexlsr} is needed to update the filename database, make it so.
\end{enumerate}
\subsection{Cautions}
\begin{itemize}
-\item The encording of your source file must be UTF-8.
+\item The encoding of your source file must be UTF-8.
\item conflicts with unicode-math
\end{itemize}
\[
0.25\,\hbox{\verb+\zw+}^{+1\,\text{pt}}_{-1\,\text{pt}} = \frac{27}{32}\,\mathrm{mm}^{+1\,\text{pt}}_{-1\,\text{pt}}.
\]
-Here \verb+\zw+ is the virtual width of `current' Japanese font.
+Here \verb+\zw+ is a counterpart of \texttt{em} for Japanese fonts, that is, the length of `full-width' in the current Japanese font.
\end{itemize}
\paragraph{Remark: Japanese Characters in Math Mode}
Since p\TeX\ supports Japanese characters in math mode, there are
sources like the following:
-\begin{verbatim}
-$T_{高圧}$, $$ y=(x-1)^2+2\quad よって\quad y>0$$
-\end{verbatim}
-However, ...
-So in this chapter, we don't describe how to change Japanese fonts in
+\begin{LTXexample}
+$f_{高温}$~($f_{\text{high temperature}}$).
+\[ y=(x-1)^2+2\quad{}よって\quad y>0 \]
+$5\in{}素:=\{\,p\in\mathbb N:\text{$p$ is a prime}\,\}$.
+\end{LTXexample}
+We (the project members of Lua\TeX-ja) think that using
+Japanese characters in math mode are allowed if these are used as identifiers.
+In this point of view,
+\begin{itemize}
+\item The lines 1~and~2 above are not correct, since `高温' in above is used as a textual label, and
+`よって' is used as a conjunction.
+\item However, the line~3 is correct, since `素' is used as an identifier.
+\end{itemize}
+
+Hence, in our opinion, the above input should be corrected as:
+\begin{LTXexample}
+$f_{\text{高温}}$~%
+($f_{\text{high temperature}}$).
+\[ y=(x-1)^2+2\quad
+ \mathrel{\text{よって}}\quad y>0 \]
+$5\in{}素:=\{\,p\in\mathbb N:\text{$p$ is a prime}\,\}$.
+\end{LTXexample}
+%BUG?: \{\}がなければ「素」がでない．上の段落の「よって」もでてない．

+どう繋ごうか？
+
+In this chapter, we don't describe how to change Japanese fonts in

\textbf{JAglue} is divided into the following three categories:
\begin{itemize}
-\item Glue/kerns specified in JFM. If \verb+\inhibitglue+ is issued,
+\item Glues/kerns specified in JFM. If \verb+\inhibitglue+ is issued,
this glue will be not inserted.
\item The default glue which inserted between two \textbf{JAchar}s ({\sf
kanjiskip}).
\item The default glue which inserted between a \textbf{JAchar} and an
\textbf{ALchar} (\textsf{xkanjiskip}).
\end{itemize}
-The value (a skip) of \textsf{kanjiskip} or \textsf{xkanjiskip} can be changed as the
-following.
+The value (a skip) of \textsf{kanjiskip} or \textsf{xkanjiskip} can be
+changed as the following.
\begin{verbatim}
\ltjsetparameter{kanjiskip={0pt plus 0.4pt minus 0.4pt},
xkanjiskip={0.25\zw plus 1pt minus 1pt}}
Lua\TeX-ja can control whether \textsf{xkanjiskip} can be inserted
before/after a character, by using \textsf{jaxspmode} and
\textsf{alxspmode} parameters.
-
-For example, the following source
-\begin{verbatim}
-\ltjsetparameter{jaxspmode={`あ,preonly}, alxspmode={`\!,postonly}}
-pあq い!う
-\end{verbatim}
-yields
-\begin{center}
+\begin{LTXexample}
\ltjsetparameter{jaxspmode={`あ,preonly}, alxspmode={`\!,postonly}}
pあq い!う
-\end{center}
+\end{LTXexample}
+
The second argument {\tt preonly} means `the insertion of
\textsf{xkanjiskip} is allowed before this character, but not after'.
the other possible values are {\tt postonly}, {\tt allow} and {\tt
\subsection{Shifting Baseline}

+the shifting of baseline of one of the pair. In p\TeX, this is achieved
by setting \verb+\ybaselineshift+ to a non-zero length (the
baseline of alphabetic fonts is shifted below). However, for documents
whose main language is not Japanese,it is good to shift the baseline of
parameter) and that of Japanese fonts (\textsf{yjabaselineshift}
parameter).
-For example, the following
-\begin{verbatim}
-\vrule width 150pt height 0.4pt depth 0.4pt\hskip-120pt
-\ltjsetparameter{yjabaselineshift=0pt, yalbaselineshift=0pt}abcあいう.
-\ltjsetparameter{yjabaselineshift=5pt, yalbaselineshift=2pt}abcあいう
-\end{verbatim}
-yields
-\begin{center}
-\vrule width 150pt height 0.4pt depth 0.4pt\hskip-120pt
-\ltjsetparameter{yjabaselineshift=0pt, yalbaselineshift=0pt}abcあいう.
+\begin{LTXexample}
+\vrule width 150pt height 0.4pt depth 0pt\hskip-120pt
+\ltjsetparameter{yjabaselineshift=0pt, yalbaselineshift=0pt}abcあいう
\ltjsetparameter{yjabaselineshift=5pt, yalbaselineshift=2pt}abcあいう
-\end{center}
+\end{LTXexample}
+
Here the horizontal line in above is the baseline of a line.
There is an interesting side-effect from that the baseline of
Japanese fonts can be shifted: characters in different size can be
vertically aligned center in a line, by setting two parameters appropriately.
-For example,
-\begin{verbatim}
+
+\begin{LTXexample}
xyz漢字
-{\scriptsize\ltjsetparameter{yjabaselineshift-1pt, yalbaselineshift=-1pt}
-XYZひらがな}abcかな
-\end{verbatim}
-yields
-\begin{center}
-xyz漢字
-{\scriptsize\ltjsetparameter{yjabaselineshift=-1pt, yalbaselineshift=-1pt}
-XYZひらがな}abcかな

+{\scriptsize

+\subsection{Structure of JFM file}
+A JFM file is a Lua script which has only one function call:
+\begin{verbatim}
+luatexja.jfont.define_jfm { ... }
+\end{verbatim}
+Real data are stored in the table which indicated above by
+\verb+{ ... }+. So, the rest of subsection are devoted to describe the
+structure of this table. Note that all lengths in a JFM file are
+floating-point numbers in design-size unit.
+
+\begin{list}{}{\def\makelabel{\ttfamily}\def\{{\char`\{}\def\}{\char`\}}}
+\item[dir=<direction>] (required)
+
+The direction of JFM. At the present, only \texttt{'yoko'} is supported.
+
+\item[zw=<length>] (required)
+
+The amount of the length of the `full-width.
+
+\item[zh=<length>] (required)
+
+\item[kanjiskip=\{<natural>, <stretch>, <shrink>\}] (optional)
+
+This field specifies the `ideal' amount of \textsf{kanjiskip}. As noted
+ in Subsection~\ref{subs-kskip}, if \textsf{kanjiskip} is
+ \verb+\maxdimen+, the value specified in this field is used
+ (if this field is not specified in JFM, 0\,pt is
+ used). Note that <stretch> and <shrink> fields are in
+ design-size unit too.
+
+
+\item[xkanjiskip=\{<natural>, <stretch>, <shrink>\}] (optional)
+
+Like the \texttt{kanjiskip} field, this field specifies the `ideal'
+ amount of \textsf{xkanjiskip}.
+
+\end{list}
+
+Besides from above fields, a JFM file have several sub-tables those
+indices are natural numbers. The table indexed by~$i\in\omega$ stores
+informations of `character class'~$i$. At least, the character class~0 is
+always present, so each JFM file must have a sub-table whose index is
+\texttt{[0]}. Each sub-table (its numerical index is denoted by $i$) has
+the following fields:
+
+\begin{list}{}{\def\makelabel{\ttfamily}\def\{{\char`\{}\def\}{\char`\}}}
+\item[chars=\{<character>, ...\}] (required except character class~0)
+
+This field is a list of \textbf{JAchar}s which are in this character
+ type~$i$. This field is not required if $i=0$, since all
+ \textbf{JAchar} which are not in any character class other
+ than 0 (hence, the character class~0 contains most of
+ \textbf{JAchar}s). In the list, a \textbf{JAchar} can be
+ specified by its code number, or by the character itself
+ (as a string of length~1).
+
+In addition to those `real' characters, the following `imaginary
+ characters' can be specified in the list:
+
+\item[width=<length>, height=<length>, depth=<length>, italic=<length>]\
+
+Specify width of characters in character class~$i$, height, depth and
+the amount of italic correction. These fields are required.
+
+
+\item[left=<length>, down=<length>, align=<align>]\
+
+These are for adjusting the position of the `real' glyph. Legal
+ values of \texttt{align} field are \texttt{'left'},
+ \texttt{'middle'} and \texttt{'right'}. If one of these
+ 3~fields are omitted, \texttt{left} and \texttt{down} are
+ treated as~0, and \texttt{align} field is treated as
+ \texttt{'left'}.
+The effects of these 3~fields are indicated in Figure~\ref{fig-pos}.
+
+In most cases, \texttt{left} and \texttt{down} fields are~0, while
+it is not uncommon that the \texttt{align} field is \texttt{'middle'} or \texttt{'right'}.
+For example, setting the \texttt{align} field to \texttt{'right'} is practically needed
+when the current character class is the class for opening delimiters'.
